Title: Heat transmission device
Inventor: JIYAKUDOU JIYUNICHI
IPC: F24J2/44
Filed: 1983-09-26
Abstract: PURPOSE:To improve the heat exchanging performance as well as the heat transmission performance in a non-powered heat transmission device for a solar water heater etc. by providing a valve in a communicating pipe between the upper part of a heat generating unit and the upper part of a liquid reservoir tank, and an auxiliary tank between the heat generating unit and the valve. CONSTITUTION:The operating medium 12 that has evaporated in a collector 1 returns to a liquid reservoir tank 7 after releasing heat to the water in a heat exchanger 2. Part of the vapor of the operating medium 12 accumulates in an auxiliary tank 14 as it replaces the operating liquid 12 in the auxiliary tank 14. When the liquid level in the tank 7 rises enough to actuate a sensor 6, a valve 10 is opened by a controller 13, and the vapor of the operating medium 12 in the auxiliary tank 14 flows into the tank on account of the pressure in the collector 1, and so, the operating medium 12 in the tank 7 is recovered by the generator 1 through a return pipe 9. When the liquid level is lowered, the valve 10 is closed to terminate the recovery so as to resume the evaporation. Thus, the heat exchanging performance and heat transmission performance can be improved.

Title: Superconducting coil
Inventor: YAMAZAKI AKINORI
IPC: H01F6/06
Filed: 1986-07-30
Abstract: PURPOSE:To eliminate gaps between a coil and a bobbin, and between coil turns in a cryogenic state thereby to obtain a stable superconducting state by pressurizing the cylindrical coil from its both sides or one side end by elastic elements. CONSTITUTION:A superconducting coil is maintained at a pressurizing force larger than a frictional force between the coil 1 and a bobbin 2 in a cryogenic state, and elastic elements 6 are so inserted to between the coil 1 and the bobbin 2 in a pressurized state at ambient temperature time as to become a stroke longer than the difference of the coil 1 and the bobbin 2 in the axial shrinkage amount due to the difference of the thermal shrinkage rate between the coil 1 and the bobbin 2. The coil 1 is brought from the ambient temperature to the cryogenic temperature to eliminate gaps between the coil 1 and the bobbin 2 and between coil turns. Thus, since no gaps exist between the coil 1 and the bobbin 2, and between the coil turns even if the coil is energized, the coil 1 is not displaced due to an electromagnetic force, i.e., no frictional heat is generated, and a stable superconducting state is maintained.
